st/nine: Improve CheckDeviceFormat debug output

Because the debug output of this function was cut in two parts,
sometimes the second part wasn't print when we would return earlier,
whereas we would like to get it.

The reason of the separation was that it's only at the end of the function
we can print what we map to the d3d9 arguments, but we can always retrieve
that info by hand.
